To all whom it may concern.'

Be it known that l, 'Mami C. izloivnrwnnr, a citizen of the United States, residing at Wabash, in the county of l/Vabash and State of Indiana, have invented certain new and useful Improvements in Fittings lor Het Water Heatingdpes, of which the follown ing is a specification. i

in those hot water heating systems in which` a plurality oi radiators are connected in arallel to a pair of circulating pipes dii' cu ty is experienced in supplying the farthest radiator with its proper proportion of hot water, owing to the fact that it is cus ternary to su ply the several radiators from the top or si e of the flow main and, as the hottest Water travels along the top of the mein, the hottest Water is always supplied to the nearest radiator.

The object of my resent invention is to rovrde means by W ich the radiators may e sup lied with water taken from the bottoms o the flow Amain and returned into the bottom of the return main, thus equalizing the circulation, and to this endl have roduced a novel and eiiicient tec fitting w ich may be used both in the flow and return mams, said fitting being preferably in a form closely resembling an ordinarytee.

The accompanying drawings illustrate my,

invention.

Figure 1 is a side elevation of a reducing tee embodying my invention; Fig. 2 a side elevation of a straight teo embed ing my in vention; Fi 3 a' transverse me iai section of the tee s own in Fig. 2; Fig. 1 a similar view of the tee shown in Fig.v 1 Fig. 5 a perspective view illustrating my improved system, with the inlets and. outlets at opposite ends oi the radiators, and Fig. 6 a similar lview using my improved valve described in Patent No. 853,364.

In the drawings, 10 indicates my im proved fitting comprising a main passage 11 equipped at each end with heads 12 adapted to receive mains 13. At one side the main body 10 is provided with a head 14 suitabl threaded to receive a tapping pipe 15. Lea ing from head 14 from the top of main bod 10 around its side, isa passage 16 whic communicates with the passage 11 through a port 17 which lies close to the bottom of passage 11, practically diametrically opposite head 14.

ln Figs. 1 and 4 one end ofthe tee is iitteuzlf1 for a smaller main than the other and the smaller opening is arranged with its top in alincmcnt with -the top of the larger() suing, so that the various sizes of mains'wi l be in line with one another, thus overcoming air pockets at the top of the mains and causing the full area of mains to be occupied by radiators 23 where, as shown in Fig. 5, the 70` piping is ofthe ordinary kind with. the circulation throu li the radiators from end to end. Ii desired, t e same systems may be used in connection with my improved valve shown in Patent No. 853,364, in which case the ar- '176 rangement will be as shown in Fig. 6.

ln operation it will be found that when the.r i. i

system is being first heated up, the gradually warming water will begin to iow' outward through flow main 20 and; because it will lie 8l) close to the top of said fiow main, it will pass ports 17 of the fittings 10 ofthe nearest radi'-l` ators and will proceed to the end of the sys,-

teln. After circulation has been established in the several radiators the cooler Water re- 85.'

turning from the radiators will pass into the bottom oi the return main below any Warnier.` returninrwater and thus prevent any tendcncv of that warmer water in the return,

main'froiii entcrin the return branches'to 90 either retard the ow in the radiators or cause a back circulation short-circuitng the end radiators.

`While the fitting which I describe is pri marily designed for use in hot water heating systems, it will be readily understood that it may also be used in rcfrigcrating systems in a similar manner but in `this case the heads 14, instead of boing directed upwardly,

should be directed downwardly so that the sup ly for the coils willbe taken'from the top of, t 1e flow main and returned to the top of the return main, the fundamental theory of the system being that the 'ports for the tapping passages shall be at a line of minimum temperature efficiency of the circulating medium, i. e., at the coolest point in temperature-raising systems and at the warmest point in temperatore-lowering systems.

l claim as my invention:

.A pipe. ttng soring of a main hollow body mvng pipe-resaivng openings of dien ent sizes in its Upposite ends, with the smalle? opening; eccentric to the larger opening, im amount substantially equa i0 the difference in radii, Said main bofy also having a ipereceing partiell leading from that si e of the ttng towmd which the smalr opening Y' of the main body is displaced, and u passage ommg s, cozmmxmctxon between sind last mentioned pipe-receiving yoron and. the

mmor of the; mam body at a pom; beyond the axis of the main body.

lu witness whereof, I, have hereunto set my hand and seal at Wbsh, Indiana, this 15th day of August, A. D. orio thousand nine hundred :md seven.
